Forward-looking statements are generally identifiable by use of forward-looking terminology such as “may,” “will,” “should,” “potential,” “plan,” “intend,” “expect,” “outlook,” “seek,” “anticipate,” “estimate,” “approximately,” “believe,” “could,” “project,” “predict,” or other similar words or expressions. Forward-looking statements are based on certain assumptions, discuss future expectations, describe future plans and strategies, or state other forward-looking information. Our ability to predict future events, actions, plans or strategies is inherently uncertain. Although we believe that the expectations reflected in our forward-looking statements are based on reasonable assumptions, actual outcomes could differ materially from those set forth or anticipated in our forward-looking statements. Factors that could cause our forward-looking statements to differ from actual outcomes include, but are not limited to, those described under the heading “Risk Factors” in our most recent Offering Circular filed with the Securities and Exchange Commission (“SEC”), as such factors may be updated from time to time in our periodic filings and offering circular supplements filed with the SEC, which are accessible on the SEC’s website at www.sec.gov. Readers are cautioned not to place undue reliance on any of these forward-looking statements, which reflect our views as of the date of this Annual Report. Furthermore, except as required by law, we are under no duty to, and do not intend to, update any of our forward-looking statements after the date of this Annual Report, whether as a result of new information, future events or otherwise.

Item 1. Business

As used in this Report, “we,” “our,” “ours,” “us,” or the “Company,” refer to Masterworks Vault 4, LLC, a Delaware series limited liability company and, as the context requires, the series of the Company and the segregated portfolios of Masterworks Cayman, SPC that holds title to the Artwork of each series, individually or collectively. “Masterworks” refers to Masterworks, LLC, and or its wholly owned subsidiaries.

Overview

We are a Delaware series limited liability company formed on August 4, 2023 to facilitate investment in distinct artworks (each, an “Artwork” and collectively, the “Artworks”). We are managed by our affiliate, Masterworks Administrative Services, LLC (the “Administrator”).

Each Artwork is owned by a separate series of the Company. Each series raises investment capital by offering Class A shares pursuant to Regulation A of the Securities Act of 1933, as amended (each an “Offering” and, collectively, “Offerings”). The Class A shares of each series represent ordinary membership interests in such series (“Class A shares”) and an investment solely in a particular series and, thus, indirectly in the Artwork beneficially owned by that series. As a Delaware series limited liability company, the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular series of the Company are segregated and enforceable only against the assets of such series under Delaware law.

On or about August 23, 2023, the Company commenced accepting subscriptions for one or more Offerings. As of December 31, 2025, aggregate subscriptions of $54,838,900 had been accepted by the Company and closed upon, resulting in the issuance of an aggregate of 2,741,945 Class A ordinary shares of various series at $20.00 per share. All of the proceeds from each Offering are used to pay, directly or indirectly, for the acquisition of Artwork, and to pay an expense allocation to Masterworks.

During all relevant times following the initial closing of each Offering, each series will hold title to the specific Artwork that it acquires in a segregated portfolio of Masterworks Cayman, SPC, or “Masterworks Cayman”, a Cayman Islands segregated portfolio company. A segregated portfolio company registered under the Cayman Islands Companies Law is a single entity which may establish internal segregated portfolios. As of December 31, 2025, no series of the Company or any segregated portfolio of Masterworks Cayman beneficially owns any material assets other than the single Artwork associated with such series or has any indebtedness or commercial obligations following the final closing of such series offering other than obligations arising pursuant to a management services agreement with Masterworks and potential contractual obligations associated with an eventual sale of the Artwork of a series.

Other than activities related to each series offering and the acquisition and maintenance of the Artworks, we have not conducted any other business activities or operations. Our strategy is to hold the Artwork for capital appreciation and to display and promote the Artwork so as to enhance its value and broaden its exposure to the art-viewing public. We will not conduct any business activities except for activities relating to the ownership, maintenance, promotion and the eventual sale of the Artwork.

We are totally reliant on Masterworks to maintain the Artwork and administer our business.

The Art Market

The global art market entered a recovery cycle in 2025 following a prolonged downturn. Combined public auction revenue at Christie’s, Sotheby’s and Phillips, rose approximately 15.5% year-over-year to $9.56 billion. This followed a significant contraction in 2024, when global auction revenue at the three major houses declined 26% to $8.27 billion as fewer major estate consignments came to market and sellers shifted toward private sales.

The recovery was heavily weighted to the second half of the year. The first half of 2025 remained soft, with auction sales at the major houses declining approximately 6% year-over-year, though the rate of decline was less severe than in prior periods. Conditions shifted decisively in the second half as several landmark single-owner collections came to market. The November New York auction season was the strongest in three years, realizing approximately $2.2 billion across the major houses, up approximately 53% from November 2024. The season was anchored by the Leonard Lauder collection, which realized $527.5 million at Sotheby’s, and included record-setting results for Gustav Klimt ($236.3 million, the most expensive Modern work sold at auction) and Frida Kahlo ($54.7 million, the most expensive work by a woman artist sold at auction). Sotheby’s auction sales rose 28.7% and Christie’s 7.2% for the full year.

Impressionist and Modern art led the recovery, with year-over-year growth of approximately 31.4%. Post-War and Contemporary art, the categories most relevant to the Company’s portfolio, remained softer, declining 17.7% and 12.3%, respectively, though buyer appetite for quality works with strong provenance remained firm. The use of third-party guarantees continued to rise, reaching approximately 73% of Post-War and Contemporary evening sale lots in the first half of 2025, the highest share since 2016.

The market for female artists continued to gain momentum, with Frida Kahlo’s record sale a notable milestone. Female surrealists including Leonora Carrington, Remedios Varo, and Leonor Fini continued to see strong demand, and Roy Lichtenstein emerged as the top-selling Post-War artist by annual sales value, driven by estate consignments.

The Post-War & Contemporary Art category has exhibited price appreciation at an estimated annualized rate of 10.24% from 1995 to 2025, versus 10.35% for the S&P 500 Index, with a correlation factor of -0.09), suggesting art’s potential as a risk diversifier.

Looking ahead through 2026, market sentiment has continued to improve following a strong New York auction season in November 2025, which saw approximately $2.2 billion in sales across Christie’s, Sotheby’s and Phillips, the strongest fall auction season in three years and up significantly from the prior year.

The strength of such a sale season can be a signal of renewed market confidence which can attract new supply of quality consignments to market, which has the effect of drawing new bidders to sales. We see this dynamic as potentially the early stages of a recovery cycle. A backlog of major estate sales, which grew over the last several years, remains a potential catalyst for further improvement in market sentiment and opportunity for price discovery. We expect the auction market to play an important role in setting the pace for this next market cycle. Geopolitics and financial-market volatility, however, remain risks to demand, particularly at the top end of the market.

Through 2025, art market transaction volumes have remained below prior periods, which has reduced near-term opportunities for artwork sales by us and by extension, capital formation for new Masterworks offerings. This has resulted in fewer portfolio exits and corresponding distributions to investors. However, we expect the renewed momentum in market sentiment to create more opportunities for exits in 2026. The Company continues to exercise flexibility in timing sales based on market conditions. For the Administrator, reduced realized sales has decreased cash flows from profit participation, though management fee accruals continue as designed.

We are otherwise not aware of any additional trends, uncertainties, demands, commitments or events that will materially affect our operations.

Administrative Services

Pursuant to a management services agreement by and between the Company, on behalf of each applicable series, Masterworks Cayman, on behalf of each applicable segregated portfolio, and the Administrator (the “Services Agreement”), the Administrator will pay all of our ordinary ongoing operating costs and expenses and manage all management services relating to our business, each series and the Artwork of each series in exchange for preferred equity interests in each segregated portfolio of Masterworks Cayman (“SPC Preferred shares”) issued at a rate of 1.5% of the total equity interests of each segregated portfolio of Masterworks Cayman outstanding, per annum. SPC Preferred shares have a liquidation preference of $20.00 per share. The Administrator will also manage any extraordinary or non-routine services which may be required, from time-to-time, including, without limitation, litigation or services in connection with a sale of the Artwork of a series or any sale, merger, third-party tender offer or other similar transaction involving us. Any third-party costs incurred by the Administrator or payments made by the Administrator in connection with litigation or major transactions will be reimbursed upon the sale of the Artwork of a series or us, as applicable. Because the Company has no employees and no liquid capital resources, the Company is totally reliant on the Administrator to maintain the Artwork of each series and administer each series’ operations. We may determine to sell the Artwork of a series without engaging a third-party intermediary, in which event, the Administrator would be permitted to charge the buyer of the Artwork of a series a reasonable fee not to exceed the lowest published buyer’s premium charged by Sotheby’s, Christie’s or Phillips in effect at such time.

Competition

At the time we attempt to sell the Artwork of a series, we may face substantial competition from other entities, such as galleries, and individuals who are selling or seeking to sell similar artworks. These other parties may be willing to sell their artworks at a lower price than us. Further, we will face significant risks from other competitive factors prevailing in the art market, such as the available supply of similar artworks for sale.

Government Regulation

As tangible personal property, art is subject to regulation under different city, state and federal statutory schemes. Generally, domestic art transactions that are conducted within the United States are subject to state Uniform Commercial Code statutes, which govern the sale of goods. Some states have additionally enacted art specific legislation, such as New York’s Arts and Cultural Affairs Law and California’s Resale Royalty Act. In addition, federal statutes such as the Holocaust Expropriated Art Recovery Act and the National Stolen Property Act can apply to title disputes in the art market context. International art transactions involving the import and export of art into and out of the United States will subject us to the rules and regulations established by the United States Customs and Border Protection. Further, we and Masterworks will be subject to the requirements of the federal Cultural Property Implementation Act which is the United States’ accession legislation for the 1970 United Nations Educational, Scientific, and Cultural Organization (UNESCO) Convention which protects countries’ cultural property, including artwork. New York City, as a major art auction center, has enacted legislation governing the activities of auctioneers in the New York City Administrative Code and Masterworks may be subject to these regulations through its transactions and financing arrangements with auctioneers.

Art transactions that cross international borders may be subject to tariffs, duties, and other trade regulations. Recent fluctuations in global trade policy may impact the art market, with certain categories of artwork facing tariffs as high as 27.5% when imported from specific countries. These tariffs can substantially affect acquisition costs, shipping logistics, and overall investment returns. Our business model requires constant monitoring of these evolving trade policies to optimize transaction structures and minimize unnecessary costs to investors. We maintain relationships with customs specialists to navigate these complexities efficiently.

The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (Patriot Act) is intended to strengthen the ability of U.S. law enforcement agencies and intelligence communities to work together to combat terrorism on a variety of fronts. The Patriot Act, to which we are subject, has significant implications for depository institutions, brokers, dealers and other businesses involved in the transfer of money. The Patriot Act required us to implement policies and procedures relating to anti-money laundering, compliance, suspicious activities, and currency transaction reporting and due diligence on customers. The Patriot Act also requires federal banking regulators to evaluate the effectiveness of an applicant in combating money laundering in determining whether to approve a proposed bank acquisition.

Risk Factors

Investing in the Class A shares of a series involves a high degree of risk and are only suitable for investors who can hold their investment for an indefinite period and can afford to lose their entire investment. The risks described in this section should not be considered an exhaustive list of the risks that prospective investors should consider before investing in the Class A shares of a series. Prospective investors should consult their accountant and other advisors as to legal, tax, business, financial, and related aspects of an investment in a series of the Company. Set forth below is a summary of certain risks that should be considered before making an investment.

Each series owns a unique artwork and whether or not a series will be able to deliver capital appreciation to investors is largely dependent on the art market, which we cannot control. We cannot make any assurance that our business model will be successful. Our operations are dedicated to acquiring and maintaining Artworks held by our series and facilitating the ultimate sale of Artworks. The ability of any series to deliver capital appreciation will depend to a large extent on economic conditions, the art market in general and the market for works produced by the specific artist, which are factors that are beyond our control. The value of an Artwork may decline after a series purchases it.

We do not expect any series to generate any material amount of revenues and Class A shares do not generate current yield. We do not expect any series to generate any material revenue, so investors will only recognize a return on their investment if the Artwork held by a series is sold or they are able to sell their shares and must be prepared to hold their investment for an indefinite period. An investment in the Class A shares of a series is unsuitable for investors seeking current yield and is only suitable for those seeking long term capital appreciation.

We are undiversified. Investing in a series is highly risky since 100% of such investment is concentrated in a single artwork.

Your ability to trade shares or otherwise exit your investment is highly uncertain. There is no active public market for the Class A shares of a series and an active trading market may not ever develop or, even if developed, may not be available to all shareholders, may not be sustained or may cease to exist. Although we facilitate or intend to facilitate secondary purchases and sales of the Class A shares of a series on an alternative trading system operating by a third-party broker-dealer (the “ATS”), certain investors are not eligible to participate on the ATS, including certain non-U.S. citizens, and it may not provide an effective means to sell your shares or receive a price for your shares that is reflective of the fair value of the Class A shares of a series or the Artwork of such series. The Class A shares of a series are thinly traded and dealers do not typically participate in the trading market, which means that trading is episodic and prices at which trades are executed often do not reflect the underlying value of the Artwork of a series. In addition, we impose restrictions on the transfer of the Class A shares of a series. Accordingly, you should consider the resale market for the Class A shares of a series to be severely limited, as you may be unable to resell your shares without significant expense or it may take a lengthy period of time to do so and you may need to offer to sell them at a price that is considerably lower than the fair value or net asset value of the Class A shares of a series..

Artwork may be sold at a loss. An artwork can decline in value and investors in Masterworks shares may lose all or a significant portion of their investment. Even if the Artwork of a series appreciates in value, the rate of appreciation may be insufficient to cover costs and expenses.

The Class A shares are illiquid. The Class A shares of a series are not eligible for trading on any stock exchange. We intend to hold the Artwork of a series for an indefinite period and the maintenance of an active trading market for the shares is uncertain. Although you may be able to sell shares on the ATS, no assurance can be given that there will be a liquid market or that you will realize fair value upon any such sale. Historically, trading in Masterworks issuer securities on the ATS has been characterized by low transaction volume and inefficient pricing. Investors should be prepared to hold their investment for an indefinite period of time, as there can be no assurance that the shares can ever be tradable or that the Artwork of a series can be sold.

Costs will diminish returns. Fixed costs, such as the expense allocation and administrative services fees paid to Masterworks and variable costs, such as Masterworks profit sharing and costs to sell the Artwork of a series, will reduce overall returns on invested capital.

Investing in art is subject to numerous risks. These risks include, without limitation (i) claims with respect to authenticity or provenance, (ii) physical damage due to improper storage, poor workmanship, accidents, theft, natural disasters, fire, etc., (iii) legal challenges to ownership, (iv) market risks, (v) economic risks, and (vi) fraud. Also, the artist that produced the Artwork could fall out of favor for a variety of reasons which would reduce an Artwork’s marketability and value. Any of these risks could reduce the value of the Class A shares of a series.

Art is illiquid. Art is a highly illiquid asset and we cannot guarantee that there will be a buyer for the Artwork of a series at any reasonable price or within any given time frame.

Trends in the art market may change. Temporary consumer popularity or trends among collectors may lead to short-term or temporary price increases, followed by decreases in value. Trends are difficult to predict and may adversely impact the value of the Artwork of a series and or our ability to sell the Artwork of a series.

Claims could cause losses. Buying and selling artwork can involve potential claims regarding title, provenance and or authenticity of the artwork. Costs associated with litigation and or settlement may be advanced by the Administrator, but are ultimately the responsibility of each series. Accordingly, the existence of any such claims may require us to sell the Artwork of a series at an inopportune time and will reduce the proceeds of a sale that are available to shareholders. Further, although we maintain authenticity and title insurance coverage, such coverage may not be sufficient against potential claims.

Insurance coverage may be insufficient. Insurance coverage may expressly exclude damage caused by war, losses caused by chemical or biological contamination and certain other potential loss scenarios. In addition, coverage limits at any point in time may be below fair value.

The Company is totally reliant on Masterworks. The Company has no liquid capital resources and is 100% reliant on Masterworks to maintain and eventually sell the Artwork of each series. If the Masterworks business model were to fail, we would likely need to sell the Artwork of each series and the timing and manner of any such forced sale may be suboptimal to maximize the sale price and value to shareholders. In addition, although we believe the Administrator has sufficient capital resources and sources of liquidity to perform its obligations under the Services Agreement for the foreseeable future, there can be no assurance that the Administrator will be able to maintain sufficient capital to satisfy its obligations in future periods.

Masterworks has conflicts of interest. Masterworks earns fees and incurs costs for administering Masterworks issuers such as the Company. Although, there is significant alignment between investors and Masterworks since Masterworks earns fees in the form of equity interests and has a profit sharing interest in each segregated portfolio, Masterworks sells a portion of its equity interests periodically and may earn money from other activities, such as for displaying the Artwork of a series, providing advisory services, future trading in the shares of a series, sale of the Artwork of a series without using a third-party intermediary or in other ways. Masterworks may have financial incentives to hold the Artwork of a series for a long time since it earns management fees for the duration of its holding period. Conversely, Masterworks may have financial incentives to sell the Artwork of a series prematurely to monetize its equity interests. Masterworks’ interests and the interests of its Board of Managers and officers may not always be aligned with your interests.

Liquidation timing is highly uncertain. There can be no assurance as to the timing of a liquidating distribution or that a series will pay a liquidating distribution at all. Investment is only suitable for those who can afford to hold their investment indefinitely and afford to sustain a total loss of capital.

The Board of Managers has complete authority to administer our business consistent with our operating agreement. Our Board of Managers has sole voting power over matters such as mergers, consolidations, acquisitions, winding up and dissolution of the Company and each individual series (as applicable). Additionally, we, in our sole and absolute discretion, may decide to sell the Artwork of a series at any time and in any manner.

The issuance of equity to the Administrator will have a dilutive effect on the holders of the Class A shares of a series and has priority upon a liquidation event. The Administrator will earn a management services fee for each series in the form of SPC Preferred shares (which are exchangeable for Class A shares of the Company). These fees will, when issued and exchanged (if applicable), effectively dilute your economic interest in the Artwork of a series. In addition, the holders of SPC Preferred shares have a $20.00 per share liquidation preference over the holders of SPC ordinary shares. In the event of a liquidation of a series, the Administrator (or an affiliate of the Administrator that holds the preferred shares of the corresponding segregated portfolio) would receive $20.00 per share of liquidation proceeds, prior to (and in preference to) the holders of the corresponding ordinary shares receiving any amount of such liquidation proceeds.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of the financial condition and results of operations of the Company should be read in conjunction with our audited Consolidated Financial Statements and the related notes.

Overview

We are a Delaware series limited liability company formed to facilitate investments in distinct Artworks by conducting an offering of Class A shares of one or more series pursuant to a Tier II offering under Regulation A+, acquiring the Artworks and maintaining the Artworks for future sale. We are managed by our affiliate, the Administrator.

During all relevant times following the initial closing of each series offering, each series will hold title to the specific Artwork that it acquires in a segregated portfolio of Masterworks Cayman, SPC, or “Masterworks Cayman”, a Cayman Islands segregated portfolio company. A segregated portfolio company registered under the Cayman Islands Companies Law is a single legal entity which may establish internal segregated portfolios. Each series owns 100% of the ordinary share capital of the applicable segregated portfolio, and such segregated portfolio will be treated as a subsidiary of the applicable series for financial reporting purposes. As of December 31, 2025, no series of the Company or any segregated portfolio of Masterworks Cayman beneficially owns any material assets other than the single Artwork associated with such series or has any indebtedness or commercial obligations following the final closing of such series offering other than obligations arising pursuant to a management services agreement with Masterworks and potential contractual obligations associated with an eventual sale of the Artwork of a series.

Pursuant to the Services Agreement among Masterworks, the Company, on behalf of each applicable series, Masterworks Cayman, on behalf of each applicable segregated portfolio and the Administrator, Masterworks manages all of our administrative services and funds all ordinary and necessary costs and expenses to maintain the Artwork of each series. In exchange for these services, the Administrator receives SPC Preferred shares at a rate of 1.5% per annum. The SPC Preferred share issuances are made quarterly in arrears and there is no overall limit to the number of SPC Preferred Shares that may be issued to Masterworks. Masterworks will be entitled to receive $20.00 per SPC Preferred share in preference to distributions to holders of Class A shares. Each series of the Company or segregated portfolio of Masterworks Cayman, as applicable, will remain obligated to reimburse the Administrator for any extraordinary or non-routine costs, payments and expenses, if any, in cash from the proceeds of a sale of the Artwork of such series, and Masterworks may also charge additional transactional fees upon a private sale of Artwork in certain circumstances.

In addition, a one-time expense allocation payment to Masterworks by each series from the proceeds of a series offering is intended to be reasonable compensation for (i) financing commitments, (ii) Masterworks’ sourcing the Artwork of such series, (iii) all research, data analysis, condition reports, appraisal, due diligence, travel, currency conversion and legal services to acquire the Artwork of such series and (iv) the use of the Masterworks platform and Masterworks intellectual property. No such charges or expenses are otherwise invoiced to the Company.

Other than activities related to each series offering and the acquisition and maintenance of the Artworks, we have not conducted any other business activities or operations. Our strategy is to display, promote and market the Artwork of each series in a manner designed to enhance its provenance and increase its exposure and its value.

We do not expect to generate any material amount of revenues or cash flow unless and until we sell the Artwork of a series. We are totally reliant on Masterworks to maintain the Artwork and administer our business. Although we believe the Administrator has sufficient capital resources and sources of liquidity to perform its obligations under the Services Agreement for the foreseeable future, there can be no assurance that the Administrator will be able to maintain sufficient capital to satisfy its obligations in future periods.

Operating Results

Our operating results for any particular series for any fiscal period following the closing date on which the applicable series offering is fully subscribed will only reflect the management services fee, which includes all ordinary and necessary operating expenses, and any extraordinary or non-recurring items for which we are responsible. Accordingly, differences in operating results from one fiscal period to the next are primarily attributable to the timing of the acquisition and disposition of the Artwork of a series. Operating results for a particular series for any fiscal period may also be affected by changes in the fair value of the Artwork of such series, since the services fee payable to Masterworks in the form of SPC Preferred shares is recorded based on the fair value of the SPC Preferred shares over the time period during which the related services are performed.

During the periods presented in the audited Consolidated Financial Statements included in this Report, neither the Company nor any series was responsible for any extraordinary or non-recurring expenses.

Contingent Liabilities

Neither the Company nor any series had any contingent liabilities as of December 31, 2025.

Income Taxes

We expect that the Company will be treated as a partnership for U.S. federal income tax purposes and not as an association or publicly traded partnership subject to tax as a corporation. As a partnership, we generally will not be subject to U.S. federal income tax. Instead, each shareholder that is subject to U.S. tax will be required to take into account its distributive share, whether or not distributed, of each item of our income, gain, loss, deduction or credit.

We had no federal and state income tax assets, liabilities or expenses (other than for management fees deducted in connection with the Services Agreement) as of and for the year ended December 31, 2025.

Liquidity and Capital Resources of the Administrator

We do not maintain any material liquid assets and, accordingly, we rely upon the Administrator to pay for the maintenance and administration of our Company and the business of each series in accordance with the Services Agreement. The table below summarizes selected unaudited balance sheet information of the Administrator as of December 31, 2025 and December 31, 2024, respectively:

We believe the Administrator has sufficient sources of current and future liquidity to satisfy its obligations under the Services Agreement for the foreseeable future. We do not believe the Company will need to raise any additional funds through the issuance and sale of securities for any series that has completed an offering in the foreseeable future, excluding management fee shares, and we are not permitted to do so under our operating agreement without prior approval of holders of the Class A ordinary shares of such series.

Masterworks, including the Administrator, has experienced considerable growth since inception in 2017, which has been funded through borrowings from Scott W. Lynn, the Founder of Masterworks and equity contributions of approximately $110 million from private investors in October 2021. Masterworks earns the vast majority of its management fees and obtains profits interests in the form of equity interests in issuers sponsored on the Masterworks Platform and periodically sells these equity interests for cash consideration. Masterworks has generated operating losses and negative cash flows from operations since 2022.

The Administrator earns fees in the form of SPC Preferred shares. Once earned the SPC Preferred shares will be exchangeable for Class A shares of the series of which the segregated portfolio holds the Artwork at an exchange rate of 1 for 1, which effectively results in dilution of other Class A shareholders of 1.5% per annum. The direct incremental costs incurred by the Administrator to satisfy its obligations under the Services Agreement are expected to be less than its revenues.

The Administrator has covenanted in the Services Agreement that for so long as such agreement remains in effect, the Administrator will maintain on hand cash reserves sufficient to pay at least one year of estimated expenses to satisfy its obligations under the Services Agreement to fund the Company’s and each series operations until the sale of the Artwork of each series. The costs incurred by the Administrator to satisfy its obligations under the Services Agreement and similar agreements for other issuers are expected to be less than its cash inflows, though such cash inflows may be insufficient to fund the Administrator’s operations and growth initiatives. Masterworks intends to fund its ongoing operations and future growth through the sale of management fee shares, together with other revenues generated by Masterworks, and may seek additional sources of third-party financing.

Masterworks entered into a revolving senior secured promissory note with the Lynn Family Trust 001 in December 2025. The outstanding principal balance of the loan as of December 31, 2025 was $7 million. The loan is secured by substantially all assets of Masterworks, including a pledge of equity interests in the Company beneficially owned by Masterworks. Other than these rights to acquire equity interests from Masterworks in the event of a default under the loan facility, Masterworks creditors have no rights, claims or interest in the assets of the Company.

The Administrator conducts other business activities, including the management of other entities similar to the Company and expects that, with scale and maturity of its operations as sales of artwork and management fee shares become a more regular occurrence, the Administrator’s cash inflows will consistently exceed its costs. The Company cannot estimate at this time what the aggregate costs and expenses of the Administrator will be with respect to such activities as they will depend on many factors. Additionally, we intend to own the Artwork of each series for an indefinite period, although we will evaluate any reasonable third party offers to acquire the Artwork of a series following the offering conducted by the series.

Commitments from Affiliates to Fund Operations

We have a written agreement with the Administrator to fund our operations and costs to maintain the Artwork of each series until we sell the Artwork or the earlier termination of the Services Agreement.

Independent auditor’s report

To the Board of Managers and Members of

Masterworks Vault 4, LLC

Opinion

We have audited the accompanying consolidated financial statements of Masterworks Vault 4, LLC (the “Company”) as a whole, on a consolidated basis, which comprise the consolidated balance sheets of the Company as of December 31, 2025 and 2024, and the related consolidated statements of operations, members’ equity, and cash flows for the period January 1, 2025 through December 31, 2025 and January 1, 2024 through December 31, 2024, and the related notes to the consolidated financial statements. We have also audited the accompanying consolidated financial statements of each listed Series of the Company, which comprise each listed Series’ consolidated balance sheet as of December 31, 2025 and 2024, and the related consolidated statements of operations, members’ equity, and cash flows for the period January 1, 2025 through December 31, 2025 and January 1, 2024 through December 31, 2024, for each listed Series, and the related notes to each listed Series’ consolidated financial statements.

In our opinion, the consolidated financial statements for the Company as a whole and for each Series referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2025 and 2024, the financial position of each listed Series as of December 31, 2025 and 2024, the results of the Company’s consolidated operations, its member’s equity and its cash flows for the period January 1, 2025 through December 31, 2025 and January 1, 2024 through December 31, 2024, and the results of each listed Series’ consolidated operations, its member’s equity and cash flows for the period January 1, 2025 through December 31, 2025 and January 1, 2024 through December 31, 2024, in accordance with accounting principles generally accepted in the United States of America.

Basis for opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements and Each Series’ Consolidated Financial Statements section of our report. We are required to be independent of the Company and each listed Series and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits and in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Responsibilities of Management for the Consolidated Financial Statements and Each Series’ Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements of the Company as a whole and each listed Series’ consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements of the Company and each listed Series’ consolidated financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability and each listed Series’ ability to continue as a going concern within one year after the date that the consolidated financial statements of the Company and each listed Series’ consolidated financial statements are available to be issued.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements and Each Series’ Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements of the Company as a whole and each listed Series’ consolidated financial statements are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with generally accepted auditing standards will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements, including omissions, are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements of the Company as a whole or on each listed Series’ consolidated financial statements.

In performing an audit in accordance with generally accepted auditing standards, we:

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control related matters that we identified during the audit.
